Power Button (PWR)-On/Off Switch

IMPORTANT: When jump starting the vehicle, turn off the radio in order to avoid damage to the sound system.

Pressing the PWR knob alternately turns the radio ON or OFF. On the UN6 and UM7, the power knob is a rotary ON/OFF switch that is shared with the volume control.
